Chromosome Reduction in Genetic Algorithms
Genetic Algorithms have been very successful as adaptive search techniques on a wide variety of problems However the GA has di culty with some problems such as those with rugged tness landscapes or those which require non binary genome representations Recent research has focused on new theories models and techniques for improving the performance of GAs on di cult problems Many new ideas have be...

متن کاملGrowing evening primroses (Oenothera)
The model plant Oenothera has contributed significantly to the biological sciences and it dominated the early development of plant genetics, cytogenetics, and evolutionary biology. The great advantage of using Oenothera as a model system is a large body of genetic, cytological, morphological, and ecological information collected over more than a century. The Oenothera system offers a well-studi...
متن کاملChromosome reduction in Eleocharis maculosa (Cyperaceae).
Chromosome numbers in Cyperaceae lower than the typical basic number x = 5 have been described for only three species: Rhynchospora tenuis (n = 2), Fimbristylis umbellaris (n = 3) and Eleocharis subarticulata (n = 3). Eleocharis maculosa is recorded here as the fourth species of Cyperaceae that has a chromosome number lower than 2n = 10, with 2n = 8, 7 and 6. The karyotype differentiation in E....
متن کاملA Contribution to an Understanding of Crossing over within Chromosome Rings of Oenothera.
There are two theories to account for linkage phenomena as observed in Oenothera. (1) Linked genes are always found within the same chromosome, that is, linkage is of the conventional or Drosophila type. The number of linkage groups is determined by the number of chromosomes in the genom, and bears no relation to chromosome configuration (SHULL 1928). (2) In addition to linkage of the ordinary ...
